Most Accurate Recording Setting?
Posted: Wed Dec 30, 2020 7:50 pm
In another thread the topic of Automatic> Most Often track recording came up:
I was wondering if GPSrChive has determined if there is really a best setting to get the most accurate track? Also what others have their 66 set at, and why.
edit: I do realize the real answer probably has "sr" in it, but for now I have the st.
And on other sites this has been discussed a bit with contradictory observations. Many say that they see more accurate tracks using Time> Once Every Second rather than the Automatic> Most Often setting. But some say just the opposite:
And the reply:If you do slow activity (f.e. hiking), I found out that smart recording is more precise because it will reduce GPS deflections.
Myself I have switched back and forth several times because I can’t really decide which gives me a more accurate track. When I have it set to Time> One Second, sometimes I think I get a less accurate track which, especially in tree cover, seems to zig zag back and forth from side to side. The “true” track seems to usually be somewhat in the center of these zigs and zags. Set to Automatic> Most Often, I get fewer Zig Zags, but the track can sometimes wander off many feet in one direction and stay there for a bit and also sometimes cut off corners or switchbacks a bit.I have no idea why this should be the case, but I have found it to be so as well. I wonder if there is some element of error-correction going on in smart recording that is absent from 1s recording. If the reception is not great (trees/buildings etc) a gps walk with 1s recording is guaranteed to give you a track with the sort of zig-zags I don't usually see on smart. For that reason alone, I generally stick with the latter. Perhaps it is the default setting for a good reason.
